Roy is correct. The issue seems to be that the large screen and the preview screen are running independent .htm files. If you choose either "*Random*" transitions or "Random order", they will each generate their own random numbers, so the random transitions between pictures will be different, and the random order will be different.

If you choose a specific transition (or "None"), and you uncheck the "Random order" check box, then they should stay pretty much in sync,... pretty much.
